BRUSH.

Be it lrnown that I, WILLIAM FEDER, a citizen lofthe United States, and al resident of the city of Chicago, inthe county` of have invented certain new and useful Improvements in Brushes; and I do Ahereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings,v and to the numerals of reference marked thereon, which form a part of this specification. A

This invention relates to brushes and processes for manufacturing the same and although not restricted to such use is particularly adapted for brushes in household use.

I have found that in many brushes the bristles are frequently not firmly secured to the head for the reason that no wedglng action is employed for holding them 1n place.

One of the principal objects, therefore, of the present invention is to provide a brush having a continuous row of bristles extending substantially the entire length of the brush.

A further object of the invention is to provide Wedging means for securing the bristles in place.

A further object of the invention is to provide an improved form of cement which is both insoluble in water and also unaffected by moderate heat.

Other and further important objects of the invention will be apparent from the disclosure in the following specification and the accompanying drawings.

The invention in a preferred form is illustrated in the drawings and hereinafter more fully described.

On the drawings:

Figure 1 is a side elevation of abroom embodying the features of the present invention.

Fig. 2 is a plan view of the head of the broom. A'

Fig. 3 is a front elevation of the head of the broom.

Fig. l is a section on the line 4--4 of Fig. E2.

Fig. 5 is a plan view of the bristles support with the top of the broom head removed therefrom.

As shown on the drawings:

The broom comprises a head 1, having a pair of diagonally arranged holes 2, foral- Specication of Letters Patent. Patented July 26|, 1921.

tornate engagement with a broom stick 3, in well known manner. The head l, includes a bristle support A, and a top piece 5, secured thereto by suitable means such as screws 6, or glue or other adhesive.

In the support A, slots 7, are formed.

Conveniently theseslots may be made byl strips are then secured in position by driving nails 10, therethrough from the sides of the support.

The ends of the bristles may be first dipped in cement, or the cement may be applied directly to the sides of the slot in the brush of bristles is then inserted into the slot either manually or by machines, and the wedge strip then driven into place.

While the wedge pieces 9, grip the ends of the bristles firmly, it is desirable to also employ cementr to hold the individual bristles together and also toy attach the bristles to the support 4:, and the wedge strips 9. I have found that a very suitable cement for this purpose may be made by mixing equal parts of shellac, white lead and rosin. This cement is'insoluble in water and is unaffected by moderate heat so that the bristles are firmly held in place at all times.

It will, of course, be evident that although two slots are shown for the insertion of bristles therein, only one may be used or if desired, a larger number than two. Also it is not essential that the wedge member be inserted down the middle of the rows of bristles as shown in the drawings as it may be inserted along one side so as to force all tpe bristles against the opposite wall of the s Ot.

After the bristles have been secured to the support 4, the projecting ends of the bristles are trimmed flush with the upper surface of the support and a layer of glueV or other adhesive applied thereto and the top piece 5, laid thereon, and further secured to the support by means of the screws 6.

Where the brush is to be used in a house, it is desirable to pad the corners of the brush and to the wedge member. The tuft l2 Y y l 1,385,532
